5 Gb/s dual-wavelength packets parallel buffering in dual-loop optical buffer(DLOB)adopting semiconductor optical amplifier(SOA)as the nonlinear element was demonstrated.

Placing gas chamber (measuring point) in DLOB, an optical fiber methane gas sensing system is designed which based on spectrum absorption methods to detect multi-point methane gas concentration by dual-wavelength in single optical path.

Research on all-optical buffer based on Arrayed-Waveguide Grating and Fiber Bragg Grating;

This paper presents a novel erasable all-optical buffer which realizes the "write" and "read" function.

An overview about the specification of all-optical buffer is given,and it is pointed out that digital buffer is not only used as a copier of input signals,but also synchronous and can be written and read out.

This paper presents an accurate model to analyze the noise characteristics and dynamic gain of re-circular all-optical buffer based on semiconductor optical amplifier(SOA) and find the intrinsic relation between SOA′s parameters and buffer′s performance.
